Usher & Mario Go Metro

Cameras caught an unglam Mario Lopez walking to Lee's Beauty Supply in Burbank ... maybe he needed a new headband to replace the one he was wearing. Lopez wasn't too thrilled about being filmed, telling cameras, "I'm lookin' tore up!" Still lookin' good.

Usher got his metro on with a shopping spree at Kitson Men on Robertson Blvd. The R&B star exited the boutique holding three full bags of make-me-look-goods from the store.

This isn't Usher's first trip down the lotion aisle -- TMZ spotted him primping at the Kalologie store last month ... it clearly takes a lotta product to look that fab.
